The traces left by the march of the ancient Greek orcs were still there, and the four of them followed the traces on the ground all the way to the west, and arrived at the junction of the Gobi and the desert around the hour.

Occasionally, you can see some green plants and small animals in the Gobi, but there is nothing in the desert except endless sand.

At this point, the traces of the orc march disappeared, and the four of them fell to the ground to drink water and rest.

After a short break, the four of them hit the road again, the desert is a forbidden area for ordinary people, but it is nothing for the cultivators who can fly through the air, the four of them can fly very high, in order to avoid the heat wave caused by the desert heat, and they also carry a Qiankun bag, which has enough food and water.

"Wu, this is still the edge of the desert. Ryan said that after entering the desert, Wu Dongfang did not travel in a straight line, and would deviate from left to right from time to time, which showed that he was looking for enemies.

"If they're really hiding in this area, they shouldn't be deep in the desert. Wu Dongfang shook his head and said.

Ryan didn't know why Wu Dongfang made such a judgment, but he didn't ask again, and followed Wu Dongfang's zigzag search.

At noon, Wu Dongfang's aura converged and fell to the ground, forcing out a large black scorpion from the gravel on the shady side of a sand dune, although this scorpion is not small, it is not the same species as the scorpion commanded by Celekert, this is an indigenous scorpion.

"Wu, I think we should search the center of the desert. "Ryan made a suggestion, it's noon, and if they can't find an opponent before dark, the situation will be very bad for them.

"Look in the middle of the desert and you may find the oases and water sources where they once settled, but their base camp will not be there. Wu Dongfang shook his head.

"Why?" asked Buck.

"This desert is endless, and if the orc legions want to cross this desert, they must choose several oases as stopovers on the way, and the frogs led by Haquet are not tolerant of drought or heat, so their last place to settle must be the place where these frogs can leave the desert and enter the Gobi overnight. Wu Dongfang explained.

Buck suddenly realized, Ryan and Injla also nodded, the differences between the East and the West are not only reflected in cultural customs, but also in people's ways of thinking, Wu Dongfang's perspective on thinking is very strange to them, but it is very accurate.

"The last place to stay should be their home base. Wu Dongfang jumped into the air, tried his best to climb, looked around from the sky, turned to lower the altitude to meet the three of them, and went north to a suspected location, where there was a little greenery, it should be an oasis with water.

Water is especially precious in the desert, where the few animals in the desert thrive on the water, including mammals such as desert foxes and camels, as well as snakes and arthropods.

Through the observation of these animals, Wu Dongfang came to a conclusion that they had not been attacked and violated before, and their vigilance was not high, and there were no injured animals among them. There are no anomalous tracks around the water source, indicating that the other party's hiding place is not in this area.

Determined that the enemy was not in this area, the four of them set out on the road again and searched north, and the search speed was fast due to the condescending observation and search, but there were no abnormal signs of the oasis and water source encountered along the way.

The ancient Babylonian method of calculating time was similar to the modern hour system, and at about two o'clock in the afternoon, the four turned back south, returning to the area where the traces of the orc march had disappeared.

"Aren't they here?" said Injla pulled out the water bladder and gave it to Buck and Ryan.

Wu Dongfang shook his head, "They are running for a long time, even if they are not here now, this area must have their foothold." ”

"But we've looked for the oases and waterholes around. Injla said that before the four of them searched north, a large area to the south had also been searched.

Wu Dongfang didn't answer, he had seen those frogs led by Hequett, and knew their moving speed, those frogs couldn't move more than a thousand miles overnight, this was still on hard soil, jumping in the desert, the speed would be greatly affected, and it would be good to be able to jump out of five hundred miles.

The reason why these frogs were chosen as references is that scorpion vipers and dung shells are drought and hunger resistant, and they can also move during the day, while the remaining aliens move very fast, and using them as references requires expanding the search radius.

"They may have gone the other way. Buck said.

"It's unlikely, for any large-scale long-distance run, there will be a makeshift camp. Wu Dongfang shook his head and said, he was born in the military, familiar with tactics and tactics, large-scale transnational operations will definitely have a relatively stable temporary base camp, which can provide nourishment and assistance to the combat troops in wartime, and if defeated, can also cover the withdrawal of combat troops.

At this moment, Wu Dongfang suddenly noticed that his positioning breath appeared somewhere in the east, and he concentrated on it and found that the place where the positioning breath appeared was the valley where Xunhuang was located.

At this time, there is no telephone telegram, and there is no way to transmit information clearly and accurately, and the parties need to judge and confirm according to the objective situation, and there is only one positioning breath, which shows that Xin Tong rushed to the ground, not Xunshuang found the enemy, and if Xunshuang found the enemy, he would definitely crush a number of positioning spirit beads.

Wu Dongfang did not rush to inform Xin Tong of their current location, first, Xin Tong must be very tired from running for a long time, and second, the four of them will not stay here for a long time, and they will be searched for next.

The induction breath interrupted his previous thinking, Wu Dongfang continued, his first thought was whether the ancient Egyptians would have a special means of transport, but this idea disappeared in a flash, and was quickly denied by him, if the ancient Egyptians really had a special means of transport, they could directly send the orc legion to the hinterland of Babylon, and there was no need to advance inland from the periphery.

Ruling out the first possibility, only the second possibility remained, that is, there must be an enemy camp within a radius of five hundred miles, but the problem is that they had searched for more than five hundred miles, and all the oases and water sources in this area had been visited, but they did not find anything abnormal.

At this point, the scrutiny has entered a dead end.

People can become very irritable in a hot environment, and it is difficult to calm down, Wu Dongfang sat down, took a tile and drew the general location of the oasis and water sources within a radius of five hundred miles from the ground, staring at these shops for consideration.

Yingjila walked over and handed a slice of bread to Wu Dongfang, "Wu, let's eat something." ”

"No, thank you. Wu Dongfang waved his hand.

Injla crouched down and looked at the figures on the sand, "If they're really in this area, they need water." ”

Wu Dongfang did not answer, after searching to no avail, Injila thought that there was no camp of the ancient Egyptian army in this area, and what she just said was actually the same meaning, they had been to these water sources within the search range, and they did not find traces of the enemy taking water near the water source, which means that the enemy is not here.

"If they really aren't here, the ensuing war will be very disadvantageous to us, and we can't be sure when, where, and how they will attack us. Wu Dongfang sighed, threw away the tiles in his hand, and took out the water altar from the Qiankun bag.

"They have suffered heavy losses, and it is not impossible for them to retreat. Injera said.

Wu Dongfang nodded, "There is also this possibility, but whether they withdraw their troops depends on how many percent of their overall strength the orc legion accounts for, if they account for more than half, then they have the possibility of withdrawing their troops." If the total annihilation of the orc legion does not hurt their bones, they will not only not withdraw their troops, but will retaliate frantically. ”

"Twelve Orcs ......"

Wu Dongfang raised his hand and interrupted Injera's words, "Don't look at the quantity, the quantity is not directly related to the entity. ”

Injla nodded in agreement and handed the slice of bread again.

Wu Dongfang waved his hand again, then grabbed the water altar and raised his head to drink water, after drinking the water, he found that Injera had not left, and he did not talk to her, put down the water altar, and picked up the tile again.

After picking up the tiles, Wu Dongfang suddenly remembered something, and pinched the tiles in his hand to look at them carefully.

"Look, is this a tile?" Wu Dongfang handed the tile to Injera.

Injla took it and looked at it, "It's edged, it should be part of the tile." ”

After Injla finished speaking, she raised her hand and showed the tiles to Buck and Ryan not far away, and the two nodded after looking at it, "It's the tiles that cover the roof." ”

Wu Dongfang didn't ask again, and Lane and the others also reacted, at this time, most of the houses were roofed with thatched or wooden boards, and very few tiles were used, for no other reason, tiles were very expensive, and ordinary people could not afford them.

This is a desert area, hundreds of miles to the east of the Gobi, and it is understandable that there are fragments of water containers here, but it is unreasonable to see tiles, because no one would carry such a thing with them, unless it belongs here.

The appearance of tiles indicates that there is likely to be a city buried in yellow sand in this area, and the tiles themselves can only be used by high-level buildings, so it can be inferred that the possible city has a certain scale.

Ryan and the others were not familiar with the situation here, they were the younger generation of Star God Fighters, but before them, there was a civil war in Babylon, and some of the oracles and Star God Fighters fled, and these oracles and Star God Fighters probably knew about the situation here and knew that there was a city buried in yellow sand somewhere near here.

If they really use this city as a base camp, they can directly use the wells in the city, and there is no need to look for water from the ground.

In addition, although he didn't know what the Undead Legion was, he roughly deduced that it should be a dark thing that could not be seen, and the dark environment underground was exactly what they needed.

Thinking of this, Wu Dongfang grabbed the water altar and drank a few sips, then put down the water altar and stretched out his fingers, "There is likely to be an underground city covered with sand in this area, find out!"
